[quote]Hi fellow flyers (in my case wannabe flyer). I am a professional spectator, my son being the flyer. Any tips on how to insulate/setup the antenna wire on a T Rex 450? We get some interference, had total loss of power on Saturday, fortunately no damage. [/quote]
I'm gonna need a little more info in order to really help but ok let's see.
Firstly is the reciever a PPM or PCM reciever? I wouldn't recommend anything but a PCM reciever on the little T-rex 450, either that or Sektrum/2.4gig stuff. The little Rex has alot of noise and static going on on it, trouble no doubt.
Secondly, never ever snip the antenna on these things. If you really want to shorten it get a proper Deans base loaded antenna and connect as per the specs. Also never ever roll the antenna up or anything of the sort.
On my T-rex before I put in a AR6100 Spektrum reciever I had the PCM reciever on the top little slanted bed. I had the antenna wire take the shortest route possible, without ever being under strain so it could damage from vibrations or anything, to the antenna tube which you install default in the skids (Install a snipped off control horn stopper here to prevent it pulling into the tube). From that I had it going through the little hole in the bottom of the vertical fin on the tail rotor (Put a small piece of heatshrink sleeve over the piece of antenna that passes through the hole so vibrations don't destroy it. From the vertical fin then back to the other side of the skids and a little rubber band connecting it to the skid so it can't be broken or anything. You don't want any piece of wire hanging loose on the heli at all either, this setup avoided that.
Next thing you want to sort of try to seperate the drive train components from the radio equipment as much as possible. Keep the ESC and it's wires on one side of the heli and the rest of the radio equipment on the other side of the heli as much as possible.
Use a ferrite bead on the ESC lead that goes to the throttle on the reciever, especially if you're using the BEC on the ESC which I'm sure you are.
Next thing is to obviously look into static electricity on the helicopter, do a little research on good you'll find alot of info about the T-rex 450 especially creating alot of static on its tail drive, there's some good and easy fixes though.
